Question

Plz help me! Find the domain and range of each function using interval notation and set builder notation.

Answer 1

Answer:

Domain:$x\ge-4$ or $[-4,\infty)$

Range: $y\ge0$ or $[0,\infty)$.

Step-by-step explanation:

The domain of a function refers to all x-values for which the function is defined.

We can see that the graph of the function is defined for all $x\ge-4$

There the domain is $x\ge-4$.

We write this in interval notation as $[-4,\infty)$.

The range refers to the y-values for which the graph is defined.

We can see that the graph of the function is defined for $y\ge0$.

We write this in interval notation as: $[0,\infty)$
